Querying Transcoding Tasks

You can query details about one or more transcoding tasks by task ID, task status, page number, start time, and end time.

If there are more than 10 records and the page number and maximum number of records on each page are not specified, 10 records are displayed by default on each page.

For details about the search criteria and search result parameters, see the API for querying transcoding tasks.
